For almost a century, Penrite has remained proudly Australian-owned and family-operated, delivering premium coolants, lubricants, additives, and cleaners trusted across industries.
Our reputation for quality, service, and performance is unmatched – and our OEM-approved coolant range is a clear example.
These are the very coolants used by leading heavy vehicle manufacturers as factory fill, protecting engines from day one.
Performance without compromise
Penrite OEM approved coolants are engineered for light and heavy commercial vehicles, mining fleets, and agricultural equipment. In many cases, they are warranty-approved for service, not just “suitable for use.”
By choosing Penrite OEM approved coolants, operators eliminate compatibility concerns, meet manufacturer specifications, maintain service intervals, and protect warranties. The advanced inhibitor packages deliver extended long-life protection against rust, corrosion, cavitation, and cooling system degradation.
The range
• Penrite EC01 Coolant: Available in both concentrate and premix, EC01 is purpose-built for heavy-duty applications. Its low depletion rate inhibitor system supports extended drain intervals – 8 years/1.25 million kilometres for on-road vehicles and 15,000 hours for off-road equipment.
• Penrite RED OEM Coolant: Approved by Cummins, MTU, MAN, Mercedes-Benz, and Scania, this Si-OAT coolant is identical to the factory-fill specification used in their vehicles. It provides robust protection in severe heavy-duty conditions.
• Penrite PGXL Coolant: A propylene glycol-based antifreeze/anti boil coolant, PGXL offers superior high-temperature stability and long-term corrosion resistance across aluminium, cast iron, brass, copper, steel, and solder. It’s specifically formulated for heavy-duty engines, including wet sleeve liners, and is trusted by Caterpillar, Cummins, DAF, Detroit, Fuso, Hino, Isuzu, MTU, Iveco, Mack, Kenworth (PACCAR) and Volvo.
Beyond these, Penrite’s OEM-approved coolant portfolio covers nearly every heavy-duty application. The Penrite Product Selector, available online and as a free mobile app for iPhone and Android, ensures the right solution is always at your fingertips.
